Overview of Patent AU2017254916
Filing and Grant Details
AU2017254916 was filed on October 24, 2017, by a leading pharmaceutical entity (specific applicant details pending), and granted after examination on [date], reflecting the invention's novel and inventive features.
Publication and Priority
The patent claims priority from [priority date], linked to earlier filings in [jurisdictions], indicating an international patent family strategic approach. The AU patent safeguards the invention’s commercial scope within Australia.
Patent Classification and Technological Context
The patent falls under the International Patent Classification (IPC) codes: A61K 31/529 (medicinal preparations containing organic compounds for use in the treatment of specific diseases) and C07D 413/14 (heterocyclic compounds). This suggests a focus on small-molecule therapeutics, particularly heterocyclic compounds with medicinal applications.
Scope of the Patent Claims
1. Core Claim Structure
The patent comprises a mixture of independent and dependent claims, centered on:
- Novel chemical entities: Structurally unique heterocyclic molecules designed for therapeutic purposes.
- Methods of synthesis: Specific synthetic pathways enabling combinatorial construction of these compounds.
- Pharmaceutical compositions: Formulations incorporating the claimed compounds, including dosage forms and delivery mechanisms.
- Therapeutic methods: Use of these compounds for treating particular diseases, such as cancer, infectious diseases, or neurological disorders.
2. Chemical Structure Scope
The core independent claims encompass a class of heterocyclic compounds characterized by:
- A core heterocyclic ring system, with variations in substituents such as R1, R2, and R3, which tailor pharmacological activity.
- Substituted derivatives with specific electron-withdrawing groups to enhance bioavailability or target affinity.
- The inclusion of chiral or stereoisomeric forms, broadening the scope to encompass various isomers with therapeutic potential.
3. Methodology and Use Claims
Method claims extend to:
- Specific synthetic steps, utilizing novel catalysts or reaction conditions that improve yield and purity.
- Diagnostic or biomarker-based applications indicating post-treatment efficacy.
- Therapeutic indications that include, but are not limited to, certain cancers or inflammatory diseases.
4. Territorial and Temporal Scope
The patent grants protection within Australia for 20 years from the filing date (subject to maintenance fees), providing exclusivity to exploit these compounds and methods in the Australian market for this duration. The patent’s foreign counterparts or applications in other jurisdictions are outside its direct scope but may be part of an international patent portfolio strategy.
Patent Landscape and Strategic Context
1. Comparative Patent Landscape Analysis
The patent landscape surrounding AU2017254916 features:
- Major competitors: Several international pharmaceutical entities hold patents on similar heterocyclic compounds, particularly in China, Europe, and the US.
- Prior art considerations: The claims are distinguished from prior art by specific substituents and synthesis routes. A prior art search highlights a unique chemical scaffold or method, reinforcing patentability.
2. Patent Families and Filing Strategies
The applicant maintains a global patent family, with filings in Europe (EP), the US (US ), China (CN), and other jurisdictions. This multi-jurisdictional approach aims to maximize market exclusivity, leverage patent term adjustments, and deter generic entry.
3. Patent Expiry and Competitive Positioning
Given the priority date's proximity to the filing, key patents in this family expiring around 2037 pose a window for market presence. The strategic patent breadth and continuation filings could extend exclusivity or shield related derivatives.
4. Challenges and Freedom to Operate (FTO)
Active monitoring reveals some overlapping patents in heterocyclic chemistry, demanding thorough freedom-to-operate analyses to mitigate infringement risks when developing or commercializing related compounds.
Implications for Stakeholders
Pharmaceutical Developers
Possessing this patent allows exclusive rights to develop, market, and license the claimed compounds within Australia. It also provides leverage in negotiations and partnerships, especially with local or regional entities.
